How can I use mixins with class-based views in Django?

You can use mixins in Django class-based views to add reusable functionality. For example, you can create a mixin for authentication.

Can you show me a simple example of a mixin?

Sure! Here's a simple mixin that requires a user to be logged in:

class LoginRequiredMixin:
    def dispatch(self, request, *args, **kwargs):
        if not request.user.is_authenticated:
            return redirect('login')
        return super().dispatch(request, *args, **kwargs)

How do I apply this mixin to a class-based view?

You can apply it by inheriting from the mixin in your view class:

class MyView(LoginRequiredMixin, TemplateView):
    template_name = 'my_template.html'

What if I want to use multiple mixins?

You can simply list them in the class definition, like this:

class MyView(LoginRequiredMixin, AnotherMixin, TemplateView):
    template_name = 'my_template.html'
